WINDIVIILL.

SPECIFIGA TION forming part of Letters Patent No. 765,036, dated July12, 1904.

Application filed December 27, 1898. Serial No. 700,360. (No model.)

To all whom it may concern:

Be it known that I, LA VERNE WV. NoYEs, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a certain new and useful Improvement in Windmills, of which thefol.- lowing is a full, clear, concise, and exact description, referencebeing had to the accompanying drawings, forming a part of thisspecification.

My invention relates to a windmill, my object being to provide animproved form of furling device for throwing the windmill into and outof the wind.

In Letters Patent N 0. 608,657, granted August 9, 1898, to Robert M.Dyer and myself, a structure is shown and claimed wherein a coiledspring is stretched between the end of the furl-lever and a point on thetail-bone near the sail, the furl-lever and the tail-bone being arrangedto be locked together when the mill is out of the wind. The presentinvention relates to an improvement and modification of thisconstruction whereby while preserving the feature of interlocking thetail-bone and the lever the structure may be rendered more compact.Accordingly the tail-bone is prolonged or extended beyond the pivot, andthe pivoted furl-lever is arranged to interlock with the extendedportion of the tail-bone, while the spring is stretched between the endof the furl-lever and a point on the tail-bone on the opposite side ofthe pivot from that of the sail, being preferably secured to a lateralarm carried on the tail-bone. The furling. mechanism is thus located ina small space and is rendered compact and is situated wholly beyond thepivot of the tail-bone, while effectively operating to throw the millinto and out of the wind and serving to lock the tail when the mill isout of the wind.

I do not claim herein the driving mechanismillustrated for operating thepump-rods or reciprocating parts, as the same forms the subject-matterof claims in another application.

I have illustrated my invention in the accompanying drawings, in which'Figure 1 is a view in elevation, partially in section, of the structureof my invention.

Fig. 2 is a sectional view on line 52 2, Fig. 1. Fig. 3 is a plan viewof the furling device when the mill is in the wind. Fig. 4 is a viewthereof in elevation. Fig. 5 is a sectional view on line 5 5, Fig. 1.

Like letters refer to like parts in the several figures.

The turn-table a of the mill is mounted to rotate about the standard aof the tower in any preferred manner and carries a pair oflaterally-extending arms a (4 which support at intermediate portions thebearing-sleeves a a in which the wheel-shaft a is journaled. The arms aa carry at the ends the bearingsleeves c a within which the journal-pinZ) is mounted, and the arm a carries in addition a bearing-sleeve a, inwhich the pivotal pin 0 of the bell-crank lever c is journaled. Upon thev journal Z) the ends 6' o of a casing I) are journaled, whereby thecasing may be rocked back and forth, the casing carrying at the oppositeend a journal-pin b", to which the pump-rod b is attached, whereby asthe casing Z2 is rocked to and fro the pump-rod b is raised and lowered.At the upper and lower edges of the casiaggtl) transverse walls 6 b areprovided adjoining the sidewalls of the casing, and these walls I) Z)serve as guideways or tracks along which the annulus or ring (Z isadapted to roll, said annulus encircling an eccentric or cam (Z, mountedupon the wheel-shaft a. Asthe wheelshaft rotates, the eccentric clmoving within the annulus (Z causes the latter to roll along theguide-wall 6, thereby raising the pumprod until in the further movementof the occentric the annulus is caused to engage and roll along thelower guide-wall I), thus lowering the pump-rod. Openings 5 b areprovided in the side walls of the casing to permit the casing to move upand down relatively to the wheel-shaft a. The annulus (Z is in practiceformed with a hollow interior, whereby an annular channel (Z is formed,which may be utilized for lubricating purposes. In the side of theeccentric d an oil-hole (Z is provided, extending obliquely andcommunicating with any one of a number of oil-holes on the innerperiphery of the annulus (Z or preferably with a channel (Z extendingcompletely around the inner periphery, whereby the oil may springconnected between the end of the furllever and the tail-bone, a pivotedbell-crank, a link extending between one end thereof and the furl-lever,and a furling wire or device extending downward from the opposite end ofthe bell-crank, substantially as described.

6. The combination with a windmill turntable, of a tail-bone pivotedthereto and having the end prolonged beyond the pivot, a furlleverhaving a part adapted to engage the prolonged end of said tail-bone anda spring connected between said furl-lever and the tailbone and adaptedto press the furl-lever against the prolonged end of the tail-bone,substantially as described.

7. The combination with a windmill turntable, of a tail-bone pivotedthereto and having the end prolonged beyond the pivot, a furlleverpivoted to the turn-table eccentric to the tail-bone and having a partadapted to engage the prolonged end of the tail-bone, means forinterlocking the furl-lever and tail-bone when the mill is out of thewind, and a spring connected between said furl-lever and the tailboneand adapted to press the furl-leveragainst the tail-bone, substantiallyas described.

8. The combination with a windmill turntable, of a tail-bone pivotedthereto at a point intermediate its ends, a furl-lever pivoted on saidturn-table and adjacent to the tail-bone and extending toward theprolonged end of the tail-bone opposite that carrying the sail, saidlever having a part adapted to engage and press against said prolongedend of the tailbone, and a spring attached to said lever at a distancefrom said pivot and extending back and attached to a point adjacent andon the tail-bone side of the pivot of the furl-lever to yieldingly presssaid lever against the prolonged end of the tail-bone.

9. The combination with a windmill turntable, of a tail-bone pivotedthereto and having the end opposite the sail prolonged beyond the pivot,a furl-lever also pivoted on said turn-table adjacent the tail-bone andextending toward the prolonged end of the tailbone, said lever having apart adapted to engage and press against the prolonged end of thetail-bone, and a spring attached at one end to the free end of saidlever and at the other end to the tail-bone at a point adjacent thepivot thereof, and on the opposite side of the tail-bone from thefurl-lever, said spring serving to press the furl-lever against theprolonged end of the tail-bone to rock the same in a direction to throwthe mill out of the wind, substantially as described.

10. The combination with a windmill turntable, of a tail-bone pivotedthereto and having the end opposite the sail prolonged beyond the pivot,a furl-lever pivoted on said turn-table upon one side of the tail-boneadjacent its pivot, said lever extending beyond the prolonged end of thetail-bone and havinga part adapted to engage and press against the sameto rock the tail-bone in a direction to throw the mill out of the wind,an arm carried upon one side of the tail-bone opposite the furl-leverand a coiled spring extending between said arm and the free end of thefurl' lever and adapted to yieldingly press the lever against theprolonged end of the tail-bone, said prolonged end of the tail-bone andfurllever being interlocked when the mill is out of the wind,substantially as described.

11. The combination with a tail-bone pivoted near one end to provide aprolonged end opposite that carrying the sail, of a furl-lever pivotedeccentric to said tail-bone and extend ing in the general direction ofsaid prolonged end, and a spring connected between said furllever andsaid prolonged end and adapted when under tension to press saidfurl-lever against said prolonged end to impart to said tail-bone atendency to move out of the wind, substantially as described.

12. The combination with a turn-table, of a tail-bone pivoted theretonear one end to provide a prolonged end opposite that carrying the sail,a furl-lever pivoted upon said turn-table eccentric to said tail-boneand at the inner side thereof and extending in the general direction ofthe prolonged end of said tail-bone, a lateral arm or projection on thetail-bone near the pivot and on the outer side thereof, a springconnected between the said furl-lever and said projection or arm andadapted to press said furl lever against the prolonged end of saidtail-bone to impart thereto a tendency to move out of the wind.

In witness whereof I have hereunto subscribed my name in the presence oftwo witnesses.
